流量计FC-2900M 

所属品牌美国TYLAN ，性价比较高。拥有3种电接口金手指、15针、9针。较广应用于半导体行业。

Autozero Digital Circuitry Automatically resets outputs to zero under no flow conditions, and shifts the entire calibration curve to cancel many effects of temperature coefficients and calibration drift. User-Selectable Response Time Options Offers a quick (0.5 second) step response time in short-cycle processes along with offering a controlled response for long processes. Temperature Coefficients Maintains tight control in varying temperatures Balanced Power Load Low lead current eliminates signal differing from its controlling device Power Operation Insensitive to power supply variations, and will operate within ± 12 volts to ± 18 volts Standard Design Industry standard pinouts and dimensions make the Tylan FC2900 easy to install in many systems

Process Values Designed to meet the exacting requirements of semiconductor processes and equipment, the Tylan FC2900 and FM3900 models are premium quality elastomer-sealed mass flow controllers and meters. These MFCs combine proven components and techniques with innovative concepts in both mechanical and electrical design.
